Have a look over these websites http://www.whatisscientology.org/ http://www.scientology.org
I wouldn't personally myself 'subcribe' to it, though the concepts seem pretty average beliefs people should have about themselves already.
thanks for the sites, i'll check them out. And no I don't think I would really find anything there of spiritual use to me but I was just curious to learn more about it just for the sake of having the knowledge. :-)
